Abstract
Process for the production of a component of valves, of fittings or of tap assemblies, including steps of providing a metal substrate, (electro-)depositing a first layer of copper on at least a portion of the metal substrate, and (electro-)depositing, on at least a portion of the first layer of copper and in direct contact therewith, a second shiny layer of chrome to obtain said component. A valve or tap assembly component made according to the aforesaid method.
Claims18
A component having a surface thereon treated, said component comprising:
- a metal substrate having an outer surface on a ball for a ball valve and at least one wall having an inner surface defining a cavity within the substrate, the outer surface and the inner surface of the cavity being coated by a first layer of copper along a portion thereof;
- and
- a coating of chrome, said coating of chrome comprising a second layer covering at least a portion of the outer surface of said first layer, said first and second layers being in direct contact.
A component having a surface thereon treated, said component comprising:
- a surface on a ball for a ball valve, the surface being coated by a first layer of copper along a portion thereof, and
- a coating of chrome, said coating of chrome comprising a second layer covering at least a portion of said first layer, said first and second layers being in direct contact.
A component having a surface thereon treated, the component comprising:
- a metal substrate having an outer surface and at least one wall having an inner surface defining a cavity within the substrate, the outer surface and the inner surface of the cavity being coated by a first layer of copper along a portion thereof;
- and
- a coating of chrome substantially external to the cavity such that one or more portions of the inner surface of the cavity are coated only with the first layer of copper, the coating of chrome comprising a second layer covering at least a portion of the outer surface of the first layer, the first layer and the second layer being in direct contact.
A component having a surface thereon treated, the component comprising:
- a metal substrate positioned in a hydraulic path and having an outer surface and at least one wall having an inner surface defining a cavity within the substrate, the outer surface and the inner surface of the cavity being coated by a first layer of copper along a portion thereof;
- and
- a coating of chrome substantially external to the cavity such that one or more portions of the inner surface of the cavity are coated only with the first layer of copper, the coating of chrome comprising a second layer covering at least a portion of the outer surface of the first layer, the first layer and the second layer being in direct contact.
A component having a surface thereon treated, the component comprising:
- a metal substrate positioned in a valve and having an outer surface and at least one wall having an inner surface defining a cavity within the substrate, the outer surface and the inner surface of the cavity being coated by a first layer of copper along a portion thereof;
- and
- a coating of chrome substantially external to the cavity such that one or more portions of the inner surface of the cavity are coated only with the first layer of copper, the coating of chrome comprising a second layer covering at least a portion of the outer surface of the first layer, the first layer and the second layer being in direct contact.
A component having a surface thereon treated, the component comprising:
- a metal substrate positioned in a valve assembly and having an outer surface and at least one wall having an inner surface defining a cavity within the substrate, the outer surface and the inner surface of the cavity being coated by a first layer of copper along a portion thereof;
- and
- a coating of chrome substantially external to the cavity such that one or more portions of the inner surface of the cavity are coated only with the first layer of copper, the coating of chrome comprising a second layer covering at least a portion of the outer surface of the first layer, the first layer and the second layer being in direct contact.
A component having a surface thereon treated, the component comprising:
- a metal substrate positioned in a tap assembly and having an outer surface and at least one wall having an inner surface defining a cavity within the substrate, the outer surface and the inner surface of the cavity being coated by a first layer of copper along a portion thereof;
- and
- a coating of chrome substantially external to the cavity such that one or more portions of the inner surface of the cavity are coated only with the first layer of copper, the coating of chrome comprising a second layer covering at least a portion of the outer surface of the first layer, the first layer and the second layer being in direct contact.
